Some Disease Determinants in the Hyperplastic Bacterial Canker of Almond Incited by Pseudomonas Amygdali

Abstract

The hyperplastic bacterial canker of almond is a disease of serious economic concern in the Aegean region and Afghanistan. The causal bacterium, Pseudomonas amygdali, incites hyperplastic cankers on branches and twigs, usually at leaf scars. The cankers, which are slow to develop, begin as swellings of the bark that crack open and become surrounded by swollen cortical tissues (Psallidas and Panagopoulos, 1975).
